We obtained new high-angular resolution data with VLT/MUSE and VLTI/GRAVITY of HR 6819. Therefore, the presence of bright sources in the 1в€’100 milliarcsec (mas) regime is a key diagnostic for determining the nature of the HR 6819 system.

Both models predict two luminous stars but with very different angular separations and orbital motions. We aim to distinguish between the two scenarios for HR 6819. Either scenario makes HR 6819 a cornerstone object as the stellar BH closest to Earth, or as an example of an important transitional, non-equilibrium phase for Be stars with solid evidence for its nature.ДЄims. Alternatively, it could be a binary composed of a stripped B star and a Be star in a close orbit.

The system could consist of a close inner B-type giant plus a black hole (BH) binary with an additional Be companion in a wide orbit. Two scenarios have been proposed to match the existing observational constraints of the object HR 6819.
